Final answer:
The Army's commitment comes from its core values which include leadership, dedication, integrity, and bravery and are demonstrated when troops support each other in adversity. American soldiers' practice of recovering all comrades shows deep commitment to these values. The Army Beta test was used to assess non-fluent English speakers for the Army.
Step-by-step explanation:
The commitment the Army demonstrates to its missions is deeply ingrained in its core values. These values are not strictly defined in the options provided but are typically understood to include leadership, dedication, integrity, and bravery. When facing adversity or unclear guidance, as described in the scenario where soldiers in Iraq supported one another despite the unclear objectives, these values are what bind them together. They are the underlying principles that guide soldiers' behavior and decision-making, fostering unity and trust among them. For instance, the willingness of American soldiers to risk their lives to recover comrades, as highlighted in Figure 11.1.5, is deeply rooted in these values and reflects the powerful bond and commitment to their mission and to each other.In response to the second part of the question, the test designed for the Army to assess recruits who were not fluent in English was known as the Army Beta test. The Army Beta test was specifically tailored for non-English speakers to measure their capabilities in a way that did not unfairly disadvantage them due to language barriers.
